上篇博客简单介绍了Restful Service的服务端编程,本篇博客详细的介绍了通过Spring集成发布服务的过程。
一、实现工具: Eclipse
二、实现过程及代码：
1、使用Maven创建web项目cxf-rs-spring
File -> New -> Others -> Maven -> Maven Project -> use default ... -> maven archetype webapp
2、配置pom.xml文件 添加依赖
4.0.0 me.cxf-sample cxf-rs-spring war 0.0.1-SNAPSHOT cxf-rs-spring Maven Webapp http://maven.apache.org 9.3.7.v20160115 3.1.6 junit junit 3.8.1 test javax.ws.rs javax.ws.rs-api 2.0.1 org.apache.cxf cxf-rt-transports-http ${cxf.version} org.apache.cxf cxf-rt-frontend-jaxrs ${cxf.version} org.apache.cxf cxf-rt-rs-service-description ${cxf.version} org.springframework spring-web 3.2.8.RELEASE org.codehaus.jackson jackson-jaxrs 1.9.13 org.codehaus.jackson jackson-xc 1.9.13org.slf4jslf4j-jdk141.7.19org.slf4jjcl-over-slf4j1.7.19 cxf-rs-spring org.eclipse.jetty jetty-maven-plugin ${jettyVersion} 3、找到文件/src/main/webapp/WEB-INF/web.xml 修改为 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > cxf-rs-spring Maven Webapp contextConfigLocation WEB-INF/beans.xml org.springframework.web.context.ContextLoaderListener org.springframework.web.util.IntrospectorCleanupListener CXFServlet org.apache.cxf.transport.servlet.CXFServlet CXFServlet /*
4、在相同目录下(/src/main/webapp/WEB-INF/)，新建beans.xml文件
创建项目，这时发现没有 src/main/java 源代码目录。 按以下步骤操作：项目名 -> Context Menu(鼠标右键) -> properties -> Java Build Path -> JRE System Lib -> Edit按钮 -> Workspace default JRE

Maven运行参数为 package jetty:run
7、 运行结果：
GET 请求
POST请求
8、 如果要输出JSON格式的文本，需要在pom.xml 和beans.xml中添加依赖， 上述代码中已添加，可自行查看
运行结果如下:
